CY74FCT2541ATQC

Overview

The CY74FCT2541ATQC is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs and three-state outputs housed in a 20-pin QSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a high-level output current of -15 mA and a low-level output current of 12 mA. Propagation delay is specified at 8 ns at 5 V. The component supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides eight-channel buffering with tri-state output capability for bus driving applications
• Utilizes Fast CMOS technology to ensure low power consumption and high-speed signal transmission
• Features dual output enable controls for flexible system integration and data direction management

Applications

• High-performance microprocessor-based systems requiring signal buffering
• Clock drivers and buffer circuits in digital communication interfaces
• Memory module address and data line buffering

Procurement Notes

Verify the specific suffix 'ATQC' against official Texas Instruments documentation to confirm the exact package type (QSOP) and temperature grade. Ensure compatibility with existing PCB footprints for 20-lead QSOP packages. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent damage during manufacturing processes.

Selection Notes

Select this component when designing systems that require octal buffering with precise timing characteristics defined by the FCT series specifications. Consider the 8 ns propagation delay and 5 V operation limits relative to connected loads. Evaluate the QSOP package constraints for thermal management and board space compared to alternative pin-compatible options like SOIC or SSOP variants within the same family.

Part Context

This part belongs to the CY74FCT2541T family of octal buffers and line drivers. It shares functional similarities with other FCT series components but is distinguished by its specific QSOP packaging and industrial temperature rating. The device serves as a critical interface element for managing data flow between high-density digital components in complex electronic architectures.
